With the implementation of waste classification policies in cities across the country,anaerobic fermentation pro-cessing has gradually become the mainstream process for kitchen waste treatment.This paper describes the design parame-ters and operation conditions of dry anaerobic fermentation process in the engineering practice of kitchen waste treatment.The actual operation results of the past two years indicate that the dry anaerobic system can operate stably in materials with high organic load and high solid content,the operating indicators such as VS degradation rate and gas production rate can reach the design level.However,the dry anaerobic system has corresponding requirements for the TS and VS of raw materi-als.Through sorting out and analyzing the operation data,the material balance equation is established through material bal-ance calculation,and the sludge yield of dry anaerobic system for kitchen waste treatment is calculated,which provides the-oretical design basis and engineering practice reference for the stable operation of the project and the design of similar pro-jects in the future.
